At the lower end of t e tape-receivxo ing com artinent of each guide-plate the pulzo its .outer end a circular end piece or cap f 12,

formed with a circumferential flange j, which engages the interior'of the pulley or drum, and also formed with a central hole through it for the stud or pin f1"y and with a circular flange f around said central hole, which extends inwardly and forms a long bearing for the pulley or drum on Vsaid stud or pin. This manner of forming the pulleys or r4drums and for supporting them is simpler 3o than the manner .shown in the patent ree ferred to and is more efficient, and the pulleys or drums are more easily placed in position at'the lower ends of the vertical tapereceiving compartments of the guide-plates. In each vertical compartment f a metallic tape h is arranged, which passes around a ulley or drum b, which is located at the ower end thereof and which is attached to said pulley or drinn, and as a ineans of attaching the tapeh to said pulley or drum .a slot h 1s formed inthe 'pulleym drurn, and a slot h2 is. formed in-the flange f of the end cap, which registers with said slot l1', and the tape passes through said slots, and the end of the ta e Which terrninates within the drinn En ley is folded upon itself, as 'shown in igs. 15 and 16, and the folded end is hound together and held hy a clipfl". The end of the tape isj thus provided with an enlargement which prevents it from being withdrawn from the pulley or drum through thc' aforesaid slots.

The upright guide plates or pieces at tho sides of the screen, whichare attached to the window-casing, are connected at their lower ends toV a bottoni casing, and said bottoni v casinar and also the means herein shown oi' attacl'lingr the lower ends of the guide-plates thereto are of novel construction.

The lbottom casing is wade as a shell and is adapted to'contain within it, and thereby inclose the screen-roll, and hence is n ade to extend from side to side of the window-cas ing. The bottom casing consists of amircularly-formed porti/on m. rising from a fiat the hole m4.

hase m', having its upper or free edge rolled, as at m2, to give to it a finished appearance and additional strength, and a lip m3, risingr from the rear edge of said base m', which extends upward a short distance. The base lm and the upturned lip mi* extend a short distance eyond the circular portion 'm at each end thereof, and the rolled edge fm2 terminates a short distance from the opposite ends of the circular portion on which it is forred, and both ends of said rolled edge are intervnally screw-threaded for a short distance,

The upturned lip r. has near each end a countersunk hole Im". The base m. has placed upon and secured to it near each end a boss m5, which is internally screw-threaded The base m has also one or more holes m located at any convenient point or points for the escape of any water which may enter the casing. The lower end of each guide-plate is constructed in a novel manner to he attached to said bottom casing. The lower end of each guide-plate rests upon the oase m of the bottoni casing, and through both walls of the vertical tapereceiving compartment holes f are punched, which register with each other and which are located op iosite the screw-threaded boss m", so that a screw f1" may he projected through said Walls and into lsaid boss, as shown in Fig. 7. The inner wall of the screen guidepassage terminates a short distance above the llower end of the guide-plate and is forned or pro vided with a rolled edge f 17, and holes are punched through the walls of the tape-receiving compartment opposite the open end of said rolled edge, and rolled edge is disposed in horizontal annenent with the rolled edge 'm2 on the cir,- cular portieri ym, and a screwf is projected through said holes in the tapeleceivi1ig cou".- partirent and through the hole in said rolled edge f and into the open end of the rolled edge m2. A conical liess f 2" is provided on the inner side of the outer wall of the screen guide-passage, which is disposed to occupy a position opposite the countersunk holc in the upturncd lip m3 and whichv is recessed to receive the y o iecting portion around said hole m.4 and which is centrally screw-threaded toA receive the screw f 21, which passes through The lower ends of the guideplates are thus securely attached to the hollow bottoni casing.

At the upper edge of the screen a cross-har is secured, consistingr of a right-angularlyforned strip of metal, comprising a vertical portion t and. a horizontal portion 'i' at the upperedge thereof, the forr-'er extendingr a short distance beyond the latter at each end, and. the screen extends up next the vertical portion on the insidel thereof and is bent over and around the horizontal portion thereof, so that the odge of the screen terminates ontop of said horizontal portion. At each end of the vertical portion 'i of the har a hole is ige ' alain.
